Asset growth and scale allows Vanguard to cut fees on its FTSE Emerging Markets Index ETF (VWO) along with seven others. The fund's drop to 0.18% from 0.20% makes it considerably cheaper than iShares' EEM (at 0.69%), which had been drawing assets from VWO as Vanguard started to re-benchmark on FTSE. The drop in fees also means VWO is now comparable in price to iShares' IEMG, though Schwab's SCHE is still the cheapest option in the space at 0.15%.
